Abstract

The invention discloses a method for determining the travel track of a mobile terminal. The method comprises the following steps: (1) removing drifting track points with abnormal distance in a track sequence by filtering; (2) if the positioning radiuses of any two or more track points which are adjacent in time in sequence in the track sequence intersect, merging the track points which serve as candidate retention track points to obtain a new track sequence which is formed by the candidate retention track points and movement track points; (3) segmenting the candidate retention track points in the new track sequence, calculating the speed of each movement track point in each track sequence segment, and removing the movement track points of which the speed is higher than the set value by filtering; and (4) setting the clustering radiuses of all the candidate retention track points in the new track sequence, and clustering the candidate retention track points in the new track sequence by taking the candidate retention track points as the center of a circle to obtain a final travel track sequence. Useless drifting track points in the travel track sequence of the mobile terminal can be removed by filtering, and thus the accurate position information and the clear travel track of a user can be obtained.

Description

technical field

[0001] The invention relates to the field of mobile terminals, in particular to a method for determining a travel trajectory of a mobile terminal. The method can accurately determine the travel trajectory of a mobile terminal. Background technique

[0002] In recent years, with the development of the mobile Internet, mobile terminal devices such as mobile phones have become quite popular, and various application services based on geographic location emerge in endlessly. The service based on geographic location includes two links, one is to use the mobile terminal to obtain the user's latitude and longitude information, and the other is to provide location-related information services. There are two main types of positioning technologies for mobile terminals:

[0003] 1. GPS positioning, the mobile terminal uses the GPS module to communicate with the GPS satellite, so that the longitude, latitude and even speed of the device can be calculated. The positionin...

Embodiment Construction

[0032] A method for determining a travel trajectory of a mobile terminal, comprising the following steps:

[0033] (1) Calculate the average velocity of each trajectory point according to the distance and time interval between two adjacent trajectory points in the trajectory sequence. When the average velocity of one or more trajectory points is greater than the set value, it is determined that these trajectory points are Drift trajectory points with abnormal distances, and then filter these drift trajectory points with abnormal distances in the trajectory sequence. Wherein, the set value refers to the maximum movement speed of the user under normal conditions, including the conditions of taking airplanes and trains.

[0034] (2) According to the positioning radius of each track point in the track sequence, each track point is judged. When the positioning radii of any two time-adjacent track points in the track sequence intersect, or any number of time-adjacent track points W...
